<p>This test covers the various ways of accessing DOM elements through
the window object by name, id or index, directly as properties of the
window object. This lookup is supposed to include embed, form,
image and object by name, and all elements by id. It should give the
element itself in the case of a single match, or an HTMLCollection in
the case of multiple matches; except that when iframes are involved,
it will give the window object for the first iframe match.
</p>

<p>Our results match WinIE in all respects but one. We allow child
frame names to take precedence over built-in and custom properties of
the window object. This is the Mozilla behavior and is required to
make some sites work because they use frame names that collide with
built-in properties in Mozilla but not IE - specifically "toobar". See
<a href="rdar://problem/3870317">Radar 3870317</a>.</p>
